A spectrophotometer consists of two instruments, namely a spectrometer for producing light of any selected color (wavelength), and a photometer for measuring the intensity of light. For solutions where intensity of light is proportional to the concentration, we use spectrophotometer.
A QA spectroscope is typically used for qualitative analysis, focusing on identifying elements in a sample. A tube spectroscope is used for quantitative analysis, measuring the intensity of spectral lines to determine concentrations of elements in a sample. Both instruments rely on the same principles of spectroscopy but differ in their applications and precision.
Metals are used in an electroscope because they are good conductors of electricity. This allows the electroscope to easily detect and respond to electric charges. Metal materials also provide durability and stability to the electroscope's components.

To determine if a metal leaf electroscope is neutral, bring a charged rod near the metal cap. If the metal leaves diverge, the electroscope is neutral. If the metal leaves collapse or diverge more, the electroscope is positively charged.
If the leaves of an electroscope hang down, it typically indicates that the electroscope is positively charged since like charges repel each other. The excess positive charge on the electroscope causes the leaves to spread apart due to the repulsive force.

telescope-is a instrument designed to gather and magnify energy of objects in space so the energy is study spectroscope-a instrument used to seprate light into very fine bands
A positively charged object will cause the leaves of the electroscope to separate or diverge. A negatively charged object will cause the leaves to come together or converge.
The plural of spectroscope is spectroscopes.
the electroscope has acquired a net charge. This charge can be positive or negative, depending on the nature of the object that interacted with the electroscope. The repulsion between the like charges on the leaves causes them to spread apart, indicating the presence of a charge.
When you touch the upper part of an electroscope with your hands, charge is transferred from your body to the electroscope, neutralizing the charge on the leaves. This causes the repulsive force between the like charges on the leaves to decrease, allowing the leaves to collapse.
...Guys...This is the answer of question...it simple! If we grounded the electroscope..whatever the charge on leaves are, positive or negative (as it depends with which charge you electrolyse the electroscope), if its positive and ground is negative (attraction) or if same + + so repultion
Yes, an electroscope can determine if an object has a charge, but it cannot distinguish between a positive or negative charge. If the object causes the electroscope's leaves to diverge, it indicates the presence of a charge on the object. Further experiments or additional methods are required to determine the polarity of the charge.
When a charged rod is brought near an electroscope, the charges on the rod repel the charges in the electroscope, causing a redistribution of charge. The leaves of the electroscope will then move further apart because like charges repel each other, leading to an increase in the separation between the leaves.

The different types of electroscopes are - i. Pith ball electroscope ii.Gold leaf electroscope iii. Needle electroscope
You can tell that an electroscope is charged by observing the divergence of the leaves. If the leaves spread apart after bringing a charged object close to the electroscope, it indicates that the electroscope has acquired a charge.
